stream replica add
Registers an existing stream as a replica of the specified stream.
adminperm
and copyperm
permissions on the stream that is
specified by the -path
parameter.mapr
user is not treated as a
superuser. MapR Streams does not allow the mapr
user to run this command
unless that user is given the relevant permission or permissions with access-control
expressions.Syntax

Parameters
Parameter | Description |
---|---|
path |
The path and name of the stream that you want to create a replica for. |
replica |
The path and name of the stream that you want to create as a replica of the
stream that you specified with the -path parameter. |
paused |
A boolean value that specifies whether to pause the replication so that it does
not start immediately. The replication can be resumed using the replica resume
command at a later time. The values are true or
false . The default is false .Set
|
throttle |
A boolean value that specifies whether to throttle replication operations.
Throttle the replication stream to minimize the impact of the replication process on
incoming operations during periods of heavy load. The values are
true or false . The default is
false .Throttling has two effects, both of which allow MapR Streams to
use more system resources to process new messages:
|
networkencryption |
A boolean value that specifies whether or not to enable on-wire encryption. The
values are true or false . The default is
false . If you set the value to true , the local
cluster and any other cluster that is part of the replication process must be
enabled for security. |
synchronous |
A boolean value that specifies whether replication is synchronous or
asynchronous. The values are true or false . The
default is false and specifies asynchronous replication. |
networkcompression |
Specifies the type of compression to use when replicating messages. For more information, see Compression. |
